Re: Unprotected and worried
Not to scare you, but my reply shouldn't have made you feel better, it should have scared you into convincing her to take some ECP.
ECP can be taken up to 72 hours after the event, and I really suggest she take it - unless she can show that it wasn't at a risky time in her cycle.
If she can't, I'd be worried that she might actually not care if she get pregnant. The time to act is now, not in a few weeks when she has some 'bad news'. When is she expecting her period?
If nothing else, maybe this lets you know how each of you feel about potentially becoming parents.
